2. The information processing apparatus of claim 1 , further comprising a display screen configured to display the content and the generated image.

3. The information processing apparatus of claim 2 , wherein the processor is further configured to control the display screen to superimpose the generated image on the displayed content.

4. The information processing apparatus of claim 2 , wherein the processor is further configured to control the display screen to display the retrieved second information associated with the at least one second word in a dedicated window on the display screen.

5. The information processing apparatus of claim 2 , wherein the interface is further configured to receive a control input from the user, and wherein the processor is further configured to control the display screen to display the retrieved second information together with the at least one second word based on the received control input.

6. The information processing apparatus of claim 1 , wherein the history information comprises: at least one fifth word searched based on a dictionary function; and a number of times the at least one fifth word is searched based on the dictionary function.

7. The information processing apparatus of claim 1 , wherein the history information comprises third information that indicates whether the second information associated with the at least one second word is to be retrieved.

8. The information processing apparatus of claim 1 , wherein the word level is determined based on a number of times the at least one second word is searched based on a dictionary function.

9. The information processing apparatus of claim 1 , wherein the history information comprises dictionary information indicative of a first genre of the at least one first word.

10. The information processing apparatus of claim 1 , wherein the processor is further configured to retrieve the second information associated with the at least one second word based on the at least one second word that has been searched within a period of time.

11. The information processing apparatus of claim 1 , wherein the processor is further configured to retrieve the second information associated with the at least one second word based on the at least one second word that has been searched more than a number of times.

12. The information processing apparatus of claim 1 , wherein the processor is further configured to retrieve the second information associated with the at least one second word based on the word level of the at least one second word that is greater than a threshold.

13. The information processing apparatus of claim 1 , wherein the processor is further configured to highlight the at least one second word in the displayed content of the generated image based on the word level of the at least one second word.

14. The information processing apparatus of claim 1 , wherein the history information comprises at least one of a search result of a dictionary function, a search result of a web browser function, a substance of registrations of an address book function, or a genre of book data that correspond to the user.

15. The information processing apparatus of claim 1 , wherein the processor is further configured to retrieve the second information associated with the at least one second word based on a user level that corresponds to the user, wherein the user level is an integer value, and wherein the user level is determined based on the history information.

16. The information processing apparatus of claim 1 , wherein the processor is further configured to retrieve the second information based on a user level that corresponds to the user, wherein the user level is an integer value.

17. The information processing apparatus of claim 1 , wherein based on reception of a control input indicative of a command to remove display of the second information at the interface, the processor is further configured to display only the at least one second word.

18. An information processing method, comprising: in an information processing apparatus: receiving an input from a user, wherein the received input identifies a content; obtaining data related to the content identified by the received input; generating history information based on user information associated with the user, wherein the user information is stored in the information processing apparatus, and wherein the history information identifies at least one first word unique to the user; determining a frequently searched genre based on the generated history information; identifying at least one second word, from a plurality of third words included in the obtained data related to the content, based on: a first comparison between the generated history information and the obtained data related to the content, and a second comparison between a genre of at least one fourth word among the plurality of third words and the frequently searched genre; retrieving related information associated with the at least one second word based on a word level of the at least one second word, wherein the word level is an integer value; and generating an image based on the obtained data related to the content and the retrieved related information.

19. A non-transitory computer-readable medium having stored thereon, computer-executable instructions for causing an information processing device to execute operations, the operations comprising: receiving an input from a user, wherein the received input identifies a content; obtaining data related to the content identified by the received input; generating history information based on user information associated with the user, wherein the user information is stored in the information processing device, and wherein the history information identifies at least one first word unique to the user; determining a frequently searched genre based on the generated history information; identifying at least one second word, from a plurality of third words included in the obtained data related to the content, based on: a first comparison between the generated history information and the obtained data related to the content, and a second comparison between a genre of at least one fourth word among the plurality of third words and the frequently searched genre; retrieving related information associated with the at least one second word based on a word level of the at least one second word, wherein the word level is an integer value; and generating an image based on the obtained data related to the content and the retrieved information.
